. To all whom it may concern:

Be it known that LCHARLES D. MoDoN- ALD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for P0? sitioning and Securing Gaskets \Vithin Metallic Caps, of which the following is a specification.

The present invention relates to a machine adapted to position a gasket of sealing substance within a metallic cap, and to form, place and secure a reta ner for said. gasketwithin'the cap.

The objects-of the present invention are, to provide a magazine adapted to receive a plurality of formed gaskets ready for positioning Within a cap; to provide mechanism for intermittently discharging the caps from the magazine; to provide mechanism for feeding the caps in a rectilinear path of travel with an intermittent movement; to provide mechanism for transferring a gasket discharged from the magazine into position within the cap, said latter action occurring during the period of rest in'the feeding of the cap; to provide means for plac-v ing a drop of acid in the cap and on that portion of the cap exposed by the opening in the gasket; to prevent the passage of more than one cap at a time from the magazine containing the caps into position to be engaged by the mechanism for feeding the caps; to provide a connection between the feeding mechanism'and the mechanism for discharging the gaskets from the magazine and positioning them within the caps, whereby the operation of the feeding mechanism also operates the mechanism for positioning the gasket within the cap and for discharging the gaskets from the magazine; to provide a movable member which will receive the gasket bearing caps after they have been carried a predetermined distance by the feeding mechanism; to provide means for cutting out from a sheet of metal having a fusible surface a blank adapted to form a retainer for'the gasket; to provide means for positioning this blank of metal upon that portion of the movable member upon which the gasket bearing caps are placed; to provide means whereby this positioning of the metal upon the movable member forms it into the necessary configuration ber"; to place this formed retainer on the member prior to the installation of the gastainer in position upon said member until the installation of the gasket bearing cap thereon; to provide means for clamping the gasket bearing cap onto the member carrying the retainer; to provide means to prevent slippag'eof the gasket bearing cap out of position prior to its being clamped upon the member bearing the retaining member; to provide means for actuating said clamping member, whereby the gasket bearing cap is held in rigid engagement with the member bearing the retainer during a pre" determined period of movement of the lat- .ter member, and the retaining member accu: rately positioned with respect to the gasket.

The'invention-further relates to means for exposing 'aportion of the cap during its conveyance by the member having the retainer thereon; and further objects are, to subject said ex'posed portion of the cap to face of the metal from which the retainer is formed is melted and the retainer is fixedly secured within the cap during the movement of the 'member carrying the retainer and the gasket bearing cap; to provide means for moving themechanism for applyingthe heat, whereby heating of the cap may be eliminated during its carriage upon the movable member; to provide-means for automatically releasing the clamping member, from clamping position, and .to automatically discharge the cap from engagement with the clamping member; and to provide a common drive shaft, the actuation of which will serve to actuate all of the mechanism constituting the apparatus for positioning and. securing the gasket within the cap.

The invention further consists in the features of construction and the combination of parts hereinafter described and claimed.

- The mechanism of the present invention is mounted upon a framework 31, which comprises an upper bed-plate 32. supported by suitable standards 33, mounted upon a base plate 34; and the standards 33 are reinforced, as shown, by suitable cross-supports 35. J ournaled 'within the standards 33 is a main driving shaft 36 for the mechanism, and, as shown more clearly in Figs. 2

and 24, said shaft '36 has mounted on one end a beveled gear 37 meshingwith a gear 38, the gear38 being secured'to' a power driven shaft 39 and suitableshifting mech anism 40 is provided for throwing the ear .38 in. and out of mesh with the gear 3 to control the stopping and starting of the machine. 4

Theupper bed-plate 32 is provided with a T-s'haped channel 41," the reduced portion 42 of said channel acting as a guideway for a feed bar 43, which extends longitudinally of the machine and is shown in detail in Figs. 10 and 11. The feed bar consists of a body portion 44, having its .upper face formed with a series of concave surfaces 45,

which provide a series of pockets or recesses 46 along the upper surface of the feed bar.

Lying within each of these pockets or recesses is a finger 47, pivoted at 48, and having its acting end,4 9 held to normally project into the enlarged portion 50 of the channel 41 by a spring 51. -Upward and downward movement of the finger around its pivotal center is limited by means ofa fixed pin 52 lying within a recess 53 in the finger..

The caps enter'into position to be engaged by the fingers and are fed forward by the action of the feed bar through a chute 54 leading from a magazine, not shown, in which the caps are-stored. An overhanging lip 55 is provided at the .point of juncture of the chute 54 and enlarged portion 50 of lip insuring the correct positioning of the cap within the enlarged portion 50 of the slot after its passage out of the chute. The

initial feed member for feeding the cap forward in the enlarged portion 50 of the channel 41 is in the form of a plate 56., best shown in Figs. 4, 5 and 6. This plate 56 is provided for the purpose of preventing the entrance of more than one cap at a time from the chute .into the enlarged portion 50, for when the plate 56 is withdrawn, as shown inFig. 5, space will be provided for a single cap to descend from the chute 54 into the position within the enlarged por.

tion'50, shown in Fig. 7.

As the feed mechanism is actuated and the bar 56 is thrown into the position shown in Fig. 4, the capdeposited from the chute 54 will be carried into position to be engaged by the fingers 47 and carried forward through the enlarged portion 50 of the channel 41; but when the plate 56 is thrown into the position shown in Fig. 4, or while it is being advanced or returned to or from said position, said plate will act as a guard to close the mouth of the chute 54 and prevent any more of the caps from entering into the enlarged portion 50 until the plate has been returned into the position shown in Fig.5. Thus the feeding of one cap at a time-from the chute into position to be acted upon by the feed bar will result.

' The feed bar is actuated with a recipro-' shaft 36. The cam engages with a roller 58' on a pivoted bar 59, and the bar is connected by a link-6O to ears 61 depending from the" a body portion of the feed bar, this? mecha-v -nism being more clearly shown in-Fig. 2.,

The ears to which the link 62 is connected are'formed as a portion of a casting 63, best shown in Fig. 9, which casting is provided with a slot 64 for the reception of a feed'bar, and is further provided with a lug 65, to which is connected 9. rodfor operating the mechanism for discharging the gasket from the hopper, which mechanism will be more fully hereinafter described. It is understood that although the plate 56 has been described separately, this plate forms in effect the feed bar, which is of a slightly different I formation from 'the balance of the feed members, namely, the fingers 47.

The casting 63 operates in a slot 66 formed in the upper bed-plate 32, best shown in Fig.

'8. Located within the enlarged portion 50 of the channel 41 are rails 67 extending longitudinally along either side thereof; and

secured to these rails are plates 68, which are of a width to slightly project beyond the rails 67' and form lips to prevent the movement upward and outward of the caps from the enlarged portion 50 during their travel therethrough. As shown more clearly in Fig. 8, the body of the cap lies within the enlarged portion 50 of the channel 41 and rests upon the face of the bottom wall of said slot; and as also shown in Fig 8, as well as Fig. 10, the acting end 49 of the finger 47 is normally held in position to project into the enlarged portion 50, whereby a movement in the direction indicated by the arrow in Fig. 10 will cause the acting end of the fingers to engage the caps and feed them along the enlarged portion 50 of the ment of the feed bar in that direction. But when the movement of the feed bar in the reverse direction takes place, the acting ends of the fingers 49will pass beneath the caps without imparting movement thereto.

Means are provided for preventing the movement of the caps with the feed bar during the return movement of the latter. These means are more clearly shown in Fig. 27, and consist of a button 68 lying within a recess 68? formed in the bed-plate 32, and said button isheld normally projected into said slot by means of a spring 68 hence, movement will only be imparted to the cap by the actuation of the feed bar in one direction, the cap remaining in its advanced position while the feed bar is returning to normal position. Thus the cap is fed through the enlarged portion 50 with. an intermittent movement.

tion, is mounted .in position to overlie centrallythe enlarged portion 50 of the channel 41 and is held in position by suitable fastening means 71 attached to plates 72 fixedly secured to theframe of the machine, the'method of securing the magazine being best shown in Fig. 1. Underlying the magazine 70 and traveling within a groove 73 in the plate 72 is a finger 74, one end of which is provided with a recess 75 of a size and form to receive one of the gaskets 70, which recess terminates in a reduced counterbore 7 6, which permits of the inser-' tion of the end of a plunger through the opening in the gasket 70, as will be more fully hereinafter explained. The opposite end of the finger 74 is formed with an upwardly projecting lug 77, in which is mounted one end of a rod 78, said rod having positioned thereon a pair of collars 79 and 80, each adjustable longitudinally of the rod. Traveling upon the rod and interposed between the collars 79 and 80 is the lug 65 of the casting 63, heretofore described and more clearly shown in Fig. 9. By

utilizing the construction embodying the collars 79 and 80, a lost-motion connection is efiected between the feed bar 43 and the finger 7 4. Said-finger 74 and its component parts form what ishereinafter termed the discharging mechanism for the gaskets.

The operation of the portion of the'device above described is as follows: Taking the Exitsas shown in Fig. 10, when the feed is moved in the dlrection of the arrow shown in saidfigure, just prior tothe end of themovement of thefeed bar in this di-' rection, the lug 65 will engage with the collar 79 and move the rod 78 in the direction of travel of the feed bar. This will efie'cta movement of thefinger 74 andwill carry the gasket contained within the recess 75 of said finger into the position. shown in Fig. "11, and the finger containing the gasket will remain in this position until the feed bar has traveled sufficient distance in the opposite direction from that indicated by the arrows ,in Fig. 10 to have *the lug 65.

engage the collar 80, after which engagement the collar will be moved in the direction of travel of the feed bar and into the position shown in Fig. 10. Thus, it will be seen that the finger having a gasketthereon Figs. 10 and 11, comprises a head 81 slidably will remain in the position shown in Fig. 11, during the period while the feed bar is traveling backward, a distance equal to the distance between the rear edgeof the lug 65 and the front face of the collar 80.

Means are provided for removing the asket from its position within the recess 75 in the finger 74 and positioning it within the cap. Said means, as shown moreclea'rly in mounted within a sleeve 82 andflheld normally projected outward from said sleeve by a spring 83, said outward movement being limited by means of a cotter pin 84, or other suitable contrivance. The sleeve 82 is carried by a lug 85 attached to a sliding bar 86, which travels within 'a grooved standard 87, more clearly shown in Fig. 1.

The bar 86 is connected to a rod 88, -upon the lower end of which is mounted aroller 89 traveling upon a cam 90, mounted upon I the main driveshaft 36; and the rod 88 is; held normally projected downward by 7 means of a coil spring 91,. this latter mechanism being best shown inFig. 2.

As shown in Fig. 28, the cam 90 comprises two cammed surfaces 92' and 93, separated-from one another by a portion 94, which in fact is part of the arcuate periphery of the disk forming the cam. Thus, as

the periphery of the disk travels beneath the roller, a doublemovelnent is given to the rod 88 during a single revolution of the shaft 36, the duration of movement of the red when engaged; by the 'cammed surface 92' being relatively short with respect to the duration of movement of the rod when the roller is engaged by the surface 93'; and the degree of movement imparted to the rod when the roller'is engaged by. the surface 92 is relatively small compared with the movement imparted to the rod when the roller engages the surface '93. This peculiar formationof cam is necessitated to give the required movement to the lug 85 to remove the gasket from the end of the finger 7 5 and.

positionit within the cap.

The operation of the ortion ofthe device just described'is as ollows: When the roller 89 engages the surface 92, sufficient movement will be imparted to the lug 85 to carry the head 81 into theposition shown in Fig. 11, where the tapered end 95 of the head 81 projects through the'hole 76 in the finger .74; and the body portion of the head is projected'through the opening in one of 'the gaskets 70,;whereby the gasket. is posi= tioned upon-the body portion of saidhead.-

After this movement which takes place wh1le the roller is traveling over the surface 92 of the cam, the lug 85, together with the head 81, is returnedto normal position, f

that is,.the position shown in Fig. 12, by the movement of the rodimparted to itby the traveling of the roller over: the surface 94 of the cam. Immediately after being re turned to normal position, the rod'is again continues in its downward movement and thesleeve 82 serves to strip the gasket offfrom the head 81 and position it-within the: I 8

cap, as shown in Fig. 10,1si1'1ce,of course,

movement of the head ischecked when the lower end thereof. shall have engaged the 4 bottom wall of the cap, and the ,sleeveis enabled to slide bythehead owingto th spring connection-between the l head and sleeve. When the gasket is stripped from the-head by the. action of thesleeve 82, the

gasket will be forced off from the body portion-of the head and will lie in a position where it will surround'the tapered end 95 of the head. Thus' as the lug 85 and its component parts are moved back "to normal position, the gasketwill remain within the cap, since the body portion of the head 81 will neverbe brought into engagement with the gasket after the gasket has been stripped therefrom,"but the gasket will continue to lie in a position where it will surround the reduced end 95' of the head. Thus, no en- 7 gagement of the gasket with the head will be effected after the gaskethas been once stripped from the head and deposited within the cap, and the movement of the head out from the cap will 'notcarry the gasket along with it; hence the gasket willremain in position within the'c'ap.

The movement of the mechanism for discharging the gasket from the magazine and gaskets out from the magazine and intoalinement with the movement of the head. '81.- The minute the gasket has assumed this positiomthe head 81 starts on its downward movement and the gasket is placed upon said head; the head is returned to normal position; and immediately when the head has cleared the finger 74, said finger starts upon its return movement,

' mediately after the head has been returned whichoccurs prior to the finishing of the stroke of the feed bar, to bring the parts into the position shown in Fig. 10. Im-

to normal position, it again starts upon its downward movement, and this time it,

is carried far enough down to position the gasket within the cap, as shown in Fig. 10. All of these movements of the head 81 occur during the period while the cap'is at rest, that'is, during the backward movement of the feed bar. Thus, during the feed of the cap, the gasketis discharged from the magazine, and during the period of rest of the cap, the gasket is transferred from'the discharging member onto a receiving member, and-from the receiving member is placed in the cap. After receiving the gasket, the cap is fed into position in alinement with a plunger 96, which is hollow and provides a reservoir 97 for containing suitable acid; The plunger 96 is carried by a bracket 98 attached to a rod 99, which is guided in its movements by a sleeve 100. The rod 99 is bifurcated at its lower end to straddle the shaft 36, and also carries at its lower end a roller 101 traveling upon the surface of the cam 102secured to the main drive shaft 36.

As the shaft 36 revolves, the cam serves to.

bringing the end 103 thereof into position cap. This mechanism consists of a table 104,

within the cap and through the opening in the center of the gasket, whereby acid discharged from the lower end of the plunger is placed upon the-surf'aceof the cap '8X- posed by the hole in the gasket. The cap with the gasket in place therein and the acid applied thereto is then fed forward into mechanism for forming, placing and securing a retainer for the gasket within the which is connected to a shaft 105 intermittently actuated by means of the engagement of a cam 106'with rollers 107 carried by-a disk 108 secured to the lower -end of-said" shaft, This construction is bestillustrated in Fig. 2, and results in an intermittent roposition by means of a bolt 111, best shown" in Fig. 16. The lower ends112 of the die members 110 are of a-configuration to provide a die surface which-acts to form the retainers into the desired configuration when said retainers are placed upon the ends of said die members.

The mechanism for cutting out the blanks from which the retainers are formed is best shown in Figs. 14, 20 and 21, and comprises a sliding head 113 operated by a rod 114 connected to an eccentric 115 upon' the shaft 36; and the head is connected to a slidable member 116, to which is also attached a boss 117 carrying the rod 114, this latter construction'being more clearly shown in Fig. 2'.

Attached to the head 113 is an arm 118, to i which is attached a link 119 connected to a bell crank lever 120, loosely mounted upon a shaft 121, upon which is mounted a feed roll 122, said feed roll, as more clearly shown in Fig. 20, being provided with knurled surfaces 123. The feedroll is actuated by means of a ratchet 124 fixedly se-" cured to the shaft 121 and operated by the engagement of a pawl 125 carried by the bell crank lever 120. Secured to the bell crank lever is a bar 126 connectedto a crank ai'm'127 loosely. mounted upon a shaft 128, upon which shaft is also loosely mounted a feed roll 129 similar to the feed roll 122.

Fixedly secured to the shaft 128 is a ratchet 130, which is operated by the engagement therewith of a pawl 131 carried by the crank arm 127. The metal is fed from a reel 132 and is maintained in engagement with the feed rolls 122 and 129 by means of suit- .able spring pressed idlers-133.

and131 are brought into acting engagement with the ratchets 124 and 130 respectively during'the movement of the head 113. in one direction; and by this engagement ofthe pawls, the feed rolls 122 and 129 are operated a predetermined distance in one direction. Thus an intermittentfeeding of the strip of metal is produced' The metal lying between thefeed rolls passes between a fixed upper plate 134 and a fixed lower plate 135, this construction being best'shown'in Fig. 23. The lower plate is provided with an opening 136 and theupper plate is provided with an opening 137, in which is positioned a female cutting die member 138 forcutting from the strip of metal the blanks from which the retainersare formed. Theof the 'diemembers for forming-the retainer.

The upper end of the plunger 139 is provided with a spring pressed plug 140, which in normal position lies flus with the top edge of the plunger 139. When, however, the blank for the retainer has been brought into engagement with the-lower end of the die member 110, the plu 140 will be deressed sufficiently so that a portion of the lankfor the retainer will be forced into the interior of the plunger 139 and the'de- ,sition.

sired configuration. given to the retainer 141, whichretainer comprises a flanged portion 142 and a countersunk central portion 143.

The operation of the above described por-' tion of the deviceais as follows: -As the head 113 is moved upward, the plunger 139 will pass throughthe opening 136-and the outer edges of the plunger 139 will act as-a male die member in conjunction with the inner edges of the female die member 138 to sever from the strip of metal a disk-shaped blank from which the retainer is forined.- This disk-shapedlblank will be carried upward by the plunger 139. and brou ht into engagement with the die face on t e lower end of the die member 110, which engagement will result inthe forming of the blank into a retainer comprising a flanged periphery: and a countersunk body portion.

The spring pressed nature of the plug 140 will insure the stripping-of the formed retainer oil from the end of the plunger 139 when said plunger is withdrawn to lowered ponut 111 which carries the die member in place within the head'109 is provided with y a bore orpassage 145 communicating with the passage 144, and connected to the nut 11 1s a bored nipple 146, to which is attached apipe 147, .the other end of which-is attached to a bored nip lo 148 in communication with the interior o a valve casing 149. This casing is attached to and" revolublp with the shaft'105. i I .v-

Located withinthe casing 149. is a valve plug 150 having a-chambered interior'l51,

with which communicates a pipe 152leading from a suitable sourceof suction. The

plug 150 is provided with a supply duct 153 and with anexhaustduct 154. As shown Asshown in Fig. 16, each of the die members 110 is provided with a bore 144 extending from end to end thereof. The

the metal surrounding-the opening,

in Fig. 14, one of the tubes 14? leads from each of the heads 109,'an d the suction'system is utilized for the purpose of maintaming the formed retainer upon the end of the die member llO'until the cap with the gasket positioned therein is placed upon the said of movement of the die member, upon'which' .the retainer is placed. After such period of movement has beencompleted, the 'suction is broken through the registration of the nipple, upon which the tube connected to this particular die member is mounted, with the exhaust port 154. However,.before this suction is broken,xthe capwith the gasket therein will have been brought into position uponthe end of thisdie member, whereby the cap will-serve thereafter to maintain the retainer in position upon thehead. But

dining-the interval of movement of the table carrying the heads 109 between the point where the retainer ,isformed and placed upon'the die members 110 and the gasket bearing caps placed. upon .said die member, the retainer will be held in" position upon the die member by meansoffthe suction heretofore described.

.To properly effect the securance of the retainer within the body of the'cap, it is necessary to provide; means to firmly position the gasket bearing cap upontheheads carry ing the retainers; and the mechanism for performing. this part of the, work is-more clearly shown in. Figs. 15,16, 17 and 18, and is as follows: P'ivoted between "ea'rs 155. carried bythe table 104' are arms 156, one of said arms being provided for each of the heads carrying the die members 110; but since the construction :and operation of all of these arms are exactly similar, it is not, deemed necessary to describe the construction andoperation ofmore than .one of them. Each ofuthe arms-is of a forked formation at its outer end-to provide an opening-I157, and the opening is of a size to receive the countersun body portion off-the cap, the flangesv of the cap' resting against cat'ed bytherlot'ted lines in Fig. 15. -1

shown in theedrawings, the slotted end of the arms is a separate piece from the body portion-of the arm, but this feature, of course, isa detail ofconstruction and could be changed to suit the idea. of the mechanic s ind-r.

building the machine. The arm is pivoted at 158 by means of a suitable pin passing 1 just described is as follows: The arms 156,

which may be termed clamping'members, are so. positioned that one of them will be at rest in alinement with the feed bar when the feed bar is operating to feed the caps.

The last finger onthe feed bar will serve to forcethe cap up onto the clamping member positioned in alinement with the feed bar, the relation of the clamping member to the feedbar being more clearly shown in Fig. 17. The rim of the cap will engage the up per face of the clamping member and serves to guide the cap so that it will position itself upon the clamping member, the countersunk body portion of the clamping member entering into the recess in the forked end of the clamping member.

As shown in. Fig. 17, when the cap is initially placed upon the clamping member,

said clamping member will be in non-acting position with respect to the head carrying til) the retainer. After the cap has beenpositioned upon the clamping member, the table 10% is rotated and the clamping member with the cap in position thereon is carried forward. In order to insure against the slippageof the cap out from its position upon the clamping member duringthe initial movement of the clamping member carrying the cap, a wall 162 is provided, which engages the outer end of the cap and holds it in the desired position upon the clamping member. After the table has been rotated a predetermined distance," the clamping member is thrown into the engaging position indioated at the left hand side of Fig. 16, which position brings the cap with the gas ket therein intofirm engagement with the die member carrying the retainer, whereby the retainer is firmly positioned in the interiorof the cap in desired relation to the gasket. This clamping position is maintained by the clamping members 156 for a predetermined period of revolution of the table 104. During the revolution of the table heat is applied to the cap by means of a series of burners 163 extending from an arcuate-shaped pipe 164, the burners 163 being in alinement with the line of travel vof the caps carriedv by the clamping .nembers 156, and are so positioned as to underlie the exposed countersunk ortions of the cap during" the periods while the table 104 is at plate 17 3.

rest. Thus, heat is applied to the cap at various intervals during the travel of the caps upon the die members 110, and the caps are maintained in the clamped position heretofore described during such application of heat. ,7

The material from which the retainers are formed is a metal having a coating of fusible material thereon. Hence, when heat is applied, the fusible surface of the retainers will melt and adhere the retainer to the interior of the cap, acid having, been placed upon the point where this fusion will take place as described in that portion of the operation pertaining to the positioning of the gasket within the cap. The cap, with the retainer positioned therein,will be carried a predetermined distance after this heating operation, and the cammed surfaces of the plates 160 and 161 will operate to release the arm 156 from clamping position and into the position'shown to the right of Fig. 16, after which an ejector 165 operated by the head 113 will serve to kick the cap out from the position upon the clamping mem ber and into any desired receptacle.

Means are provided for moving the burners out from position in the line of travel of the caps, said mechanism comprising a rod 166, which'is connected by a link 167 to the clutch mechanism 40. The rod 166 is operated by a handle 168, whereby the-revolution of the rod by the swinging of the handle will throw the link 167 to break the clutch connection to the driving mechanism. At the opposite" end of the rod is a link 169 which is connected to an arm 170 pivotally secured to a bracket 171. The upper end of the arm 170 is connected -to a plate 172, which is slidably mounted upon a fixed By this construction, when the rod 166 is rocked to throw the clutch mechanism out of engagement, the link 169 is swung to actuate the arm 170 and slide the plate 17 2, which carries the pipe;164,whereby the pipe is moved outward from the cenpath of travel of the caps carried by the die 1 members 110.

By the above arrangement, whenever the operation of the machine is stopped by the throwing out of the clutch gearing, the heating mechanism is simultaneously thrown out of activeoperation, and thus the danger of a continued heat being applied to the caps during a. long period of rest of the machine is obviated, as is also the necessity of cutting off the supply of heat by the operator each time the machine is-stopped. The relation of the periods of rest and the periods of movement of the'several-parts is as follows The period of movement of the table 104 is during the period of rest of the cap being fed by the feed bar. The period of movement of the mechanism for forming and placing the retainer upon the head and for ejecting the completed cap from the clamping member, as well as the mechanism for centering the table 104, occurs during head 113. It will be noted that the mechanism for formingand placing the retainer, the mechanism-for centering the table 104, and the mechanism for ejecting the cap from the clamping member, are all carried and operated by the movements of the slidable member 116.]

The operation of the entire machine will 'be understood from the. foregoing, but

briefiyis as'followszThe caps are fed through the actuations of the feed bar 43 into position to receive the gaskets discharged from the magazine 69. After the gaskets have been positioned within the cap,

acid is placed in the cap on the portion vexposed by the hole in. the center of the gasket. The cap is then fed forward into position to be received fby the clamping members 156. Priorto the reception of the caps by the clamping members, aretainer has been formed and placed upon the die carried by the heads 109, and said retainer is'held in position upon said heads, prior to the positioningof the cap thereon, bymeans of suction. When the head with the retainer is brought into proper position, the cap with the gasket thereon is fed ontO the clamping member and the clamping member actuated to bring the gasket bearing'cap into firm and accurate position with respect to the retainer carried upon the head. Then the table 104 continues in its revolution, and during such revolution the clamping member is actuated to hold the gasket bearing cap in its clamped posit-ion the cap, whereby the fusible surface of theupon the head carrying the retainer, and during such engagement heat is applied to retainer is melted and the retainer fixed within the body of the cap. After this has been accomplished, the clamping member is released from its engaged position and. the cap is ejected from its position uponthe clamping member through theactuation" of the ejecting member 165. While the table 104 is at rest, the. head 113 will be actuated toraise the plunger 139, which cuts the blank from the retainer out from i the body of-the metal, as well ascarries the blank upon the die 110 to form the-same, and at this same operation the pilot-pin 176 will be advanced to engage with the reveyed by the receiving member, substan- 'a plurality of members adapted to receive combination of a carrier provided cess in the heads 174, whereby a centering of the table 104 will,be effected during each period of rest thereof; and at the same time that the cutting and forming of the re tainer occurs, the ejector-165 will be operated to discharge the completed cap from its position upon the clamping member.
